After establishing a new safehouse for the Railroad, the Caretaker will request that the Sole Survivor clear a random location of its hostiles so that a synth, whose designation starts with K8, will be able to leave the Commonwealth safely. Once all enemies in the location have been killed, return to the Caretaker to complete the quest.
Mercer's new Railroad agent, Caretaker, needs to help a tourist so he in turn can help one of our Synths escape the Commonwealth. The details are scarce. Go to the target location and eliminate all hostiles.
Eliminate the threat at (location)
Report back to Caretaker
Well, the hostiles were eliminated. Hopefully that'll make it so the tourist is willing to work with us. I should report this to Caretaker back at Mercer Safehouse.
Caretaker said that the tourist is already working for us and K8 is being moved out of the Commonwealth. Mission accomplished.
PC If the area assigned has already been cleared out, then the player character may have difficulty with quest completion.[verified]
To counter this bug on PC use console and insert: setstage 000b3e82 300. This will mark the 'eliminate target' as completed and will let the player character talk to the Caretaker (be safe and check it with sqo 000b3e82).
PCPlaystation 4 The marked enemy may not appear if the location is visited after purchasing the Automatronadd-on.[verified]
